Baseline flowsheet model for IGCC with carbon capture / Randall P. Field in Industrial & engineering chemistry research, Vol. 50 N° 19 (Octobre 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 19 (Octobre 2011) . - pp. 11306-11312 Titre : Baseline flowsheet model for IGCC with carbon capture Type de document : texte imprimé Auteurs : Randall P. Field, Auteur ; Robert Brasington, Auteur Année de publication : 2011 Article en page(s) : pp. 11306-11312 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Modeling  Flowsheet Résumé : Integrated gasification combined cycle (IGCC) processes have the potential for high thermal efficiency with a low energy penalty for carbon capture. Many researchers have proposed various innovations to improve upon the efficiency of the IGCC process. However, the analysis methods of most publications are generally not transparent and these published results are exceedingly difficult to reproduce. The National Energy Technology Laboratory (NETL) report [Cost and Performance Baseline for Fossil Energy Plants: Bituminous Coal and Natural Gas to Electricity Final Report; U.S. Department of Energy, Office of Fossil Energy, NETL, DOE/NETL-2010/1397, 2010] is widely used as a reference by researchers and by industry. To enable researchers to have a consistent and transparent framework for analyzing IGCC flowsheets and potential innovations, a baseline model derived from the NETL report is described herein and the corresponding flowsheet model and its full documentation are available online from this journal for use and modification.

Performance of an IGCC plant with carbon capture and coal - CO2 - slurry feed / Cristina Botero in Industrial & engineering chemistry research, Vol. 51 N° 36 (Septembre 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 36 (Septembre 2012) . - pp. 11778-11790 Titre : Performance of an IGCC plant with carbon capture and coal - CO2 - slurry feed : Impact of coal rank, slurry loading, and syngas cooling technology Type de document : texte imprimé Auteurs : Cristina Botero, Auteur ; Randall P. Field, Auteur ; Robert D. Brasington, Auteur Année de publication : 2012 Article en page(s) : pp. 11778-11790 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Cooling  Synthesis  gas  Loading  Carbon  dioxide  Coal Résumé : The high heat capacity and latent enthalpy of vaporization of water lead to a low gasification efficiency in gasifiers fed with coal-water slurry. Liquid carbon dioxide, CO2(1), has been suggested as an alternative slurrying medium to improve the efficiency of low-rank coal gasification in integrated gasification combined cycle power plants with carbon capture. Steady-state process simulation is used in this work to confirm published findings and present a comprehensive assessment of the impact of the coal rank, gasifier cooling technology, and CO2 slurry loading uncertainty on the performance advantage of CO2 slurry-fed plants. A power generation efficiency improvement of up to 25% (5%-points) is predicted, which is shown to increase with decreasing coal rank and to be highest for full-quench gasifier cooling technology; the latter is a significant source of capital cost savings and is especially attractive when combined with CO2 slurry feed. Using CO2(1) instead of water slurry reduces the performance penalty of low-rank coal gasification by half, thus substantially improving the feedstock flexibility of the plant. With a single exception, the performance benefit of coal-CO2 slurry was found to be outside the uncertainty range of the slurry loading, which is still one of the key unknowns of this alternative feed system.
